EXAM QUESTIONS AND ANSWERS
Given the following set of numbers: 3.3, -2.3, -16, 25. What are
the square roots of the whole number?
A. +/- 2.3
B. +/- 3.3
C. +/- 4
D. +/- 5 - ANSWER-D. +/- 5
Composite Number - ANSWER-A number with more factors
that just one and itself.
Equivalent Fractions - ANSWER-Different fractions that
represent the same value.
X-Axis - ANSWER-The horizontal line that passes through the
origin on a coordinate plane.

Qualitative Data - ANSWER-Non-numeric information based on
some quality or characteristic.
No Correlation - ANSWER-There is no apparent overall trend
between the two variables. If the correlation coefficient is 0, this
only rules out a linear trend. There could be a non-linear or
curvilinear trend.
Extrapolate - ANSWER-Using information from a data set to
make predictions about data outside of the original set.
Event - ANSWER-An outcome, or set of outcomes, whose
chance of occurrence can be represented with a probability.
Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is
the sum when adding together only the whole numbers?
A. 5.5
B. 11
C. 12.5
D. 15 - ANSWER-D. 15

Operation - ANSWER-In Mathematics, an operation is a
procedure which generates a new value from one or more
operands, or Mathematical values.
Conditional Proportion - ANSWER-A proportion where one part
of the proportion is a variable, or unknown quantity.
Coefficients - ANSWER-A number by which a number is
multiplied. This number is written in front of the variable(s).
Mean - ANSWER-Average, calculated by adding a series of
elements in a data set together and dividing by the total number
in the series.
Outlier - ANSWER-An observation point that is statistically
distant from the other observations in the dataset.
